K f y A further object is to provide anovel construction wherein novel roller bearing means are provided andthe housings therefor extend from one wheel towarditlie other andterminate relatively close together and are connected in a novel mannerso that the wheels may be independently removed, re-

paired and parts replaced. 1

It is further aimed to provide a novel construction of endmounting ofthe axleV with respect tothe truck pedestal. Various additional objectsand advantages will become apparent from a, consideration ofthedescription following taken in connectionywith accompan ing drawingsillustrating an operative em odiment.

In said drawings k Figure 1 is a view in elevation illustrating theinvention in connection with an'axle and pair of wheels, f Y y Figure 2`s across sectional view taken on the line 2-2 of Figure 1, 3o Figure 3is a substanti tudinal sectional view taken through one ot the wheelsand associated partszand a portion of the associated parts of thecompanion wheel,

edesignates conventional railway car Wheels adapted for free mounting ona conventional axle 11 whose ends are reduced as at 12 providingshoulders 13. Reduced portions 12 are fastened in blocks 14 by means ofpins 15, preferably removable, or otherwise.

Blocks 14 maybe mounted according to any of the existing methods, thatis,fbe slidably mounted in-and for movement relatively to the pedestalsof a truck or be rigidly mounted in the truck pedestal and the latter beadapted to slide and carry the same therewith. Associated witheach'whcelV 10 is an vanti-friction bearing housing 16 and the wheels 10are rigidly connected thereto in any suitable manueras by press-fittingthc same against an abutment 17 thereon. Thus the housings 16rotate withthe wheels 10 and they have terminal orend flanges 18 and 19, eachfianga extending inwardly and being provided with gaskets or the like 20adapted to wipe against the axle 1'1 to preventthe escape of lubricantfrom the interior of the housings 16. The

flanges 18 abut the shoulders 13.

An important feature of the present invention resides in the elongationof the housings 1'6 so that they substantially meet midway of the endsof the axle 11. At the meeting ends, housings 16 are connected togetherby a'coupling ring 21 which may be made-in any desired form. As shown,the ring 21 comprises a plurality of separablesegmental sections 22which are secured detachably A together by means of bolts 23.

.The fit betweenthe couplings 21 and the housings 16 is loose enough topermit relative rotary movement of he housings 16 and wheels 10 as isrequisite when rounding curves. Itwill be notedthat the portions 19 areextended outwardly beyond the periphery to provide flanges 24 and thatsuch fianges are accommodated in annular grooves 25 provided in thesections 22 of the couplings.

In each housing 16, suitable anti-friction bearing devices are provided.To this end, inner races 26 may be press-fitted tightly to the axles 11vadjacent each end of each housing 16 and the Vhave cooperating races 27,loose or presstted within the housings 16. Between the races 26 and 27,anti-friction members 28 are disposed 'and the may be in the vform ofballs or rollers an the latter may bek cylindrical, tapered or of anypreferred form. End rings 29 are located between the .rac-es 26 andV 27and serve to properly position'the bearings 28.

2 y Lacasse Between-each pair of anti-friction devices, a spacing cage30 is provided, the same havving inwardly extending anges 31 abuttingthe ends of the races 26 and 27 and adjacent- 5 rin'gs 29, such cagebeineF perforated as shown at 32 for free flow' of lubricanttherethrough.

It will be realized thatnthe housings 16 arc filled with lubricant, andto facilitate the flow thereof, the races 27 may have ports 33-there- 1gthrough. 32 indicates conduits in the races 27 communicating with theorts 32 and 33 to permit circuiation of the 1u ricant.

Various changes may be resorted to provided they fa-ll within the spiritand scope of the invention. For instance one modified form is shown inFigure 4. In this form, the

housing equivalent to that at 16 is designated 16 and it is closed atits outer end by a separate end plate18, which is secured as 20 at 18"to the housing 16 `by press-fitting, bolting or in any desired manner.About the axle each portion 12', equivalent to that at 12,

the end closure 18 has an annular collar or extension 13 which extendsinto and interits with the block 14', equivalent to that at 14 of thereceding form.

Another modified form is illustrated in Figure 5 which may employ aplate or disk 34 interfittin with an extension 35 on the outer end wa 16of the housing equivalent .to that at 16. The block 36 is equivalent tothat at 14 and 14 and it has a recess at 37 accommodating aninterfittinprojection or struck out portion on the disk 34. One or 35 more screws38 may be threaded on the block 36 and are adapted to be moved againstthe `plate 34 in order to impart longitudinal movement to the housing 16and wheel carried thereby to properly and adjustably position 40 thesame.

Referring to the further modified form shown in Figure 6, a sectionalcoupling 22 is em lo ed in lieu of that at 22, its parts being of q'-`lyiape in cross section so as to have a flange 22 overlapping theperipheries of housings 39 equivalent to thc-se at 16 but devoid o theflanges 25. This particular form also provides a flange or web at 40which is disposed intermediate the ends of the housin 39.

It will be obvious that the screws 38 may be em loyed in each of thepreceding .forms and abut directly7 a ainst the housings and that suchforms can in such screws, since the section lines are ta en at locationswhere the screwsdo not appear.

I claim as my invention 1. In combination, a relatiy ely fixed axle, 6 apluralit of wheels, said wheels having housings t ereon, means joiningthe housings v and permitting relative movement thereof,
